you better do this then ABS Mod - LAND ROVER CLUB V.I. , option B...and it'll be fixed for good(but only for SVS failure...other faults will still trigger the 3 amigos)

You beat me to that link by seconds...was just about to post the same.

Mine's also got SVS 'electrical failure' and this spring I'll also be undertaking 'Option B'.

Please let us know how you got on, especially as I've had one crack at this and couldn't lift the ABS unit high enough to get at the allen screws beneath in the modulator unit. I'd love to know if you achieve this and how.

Cheers
Lea

Watched the vid, seems like with a short angled allen key you can get at the allen screws?

Straight forward undo the 2 electrical connectors then undo four bushs take brake lines of brackets which are onto bulk head then just lift it up I just held it up while I undid the 3 x 4mm hex holding shuttle valve in place

I just couldn't lift mine up for fear of damaging the brake lines going to the top of the ABS....The 3 x 4mm hex holding the shuttle valves are beneath the ABS right, so lift up the ABS (mine only lifts 75mm safely) and slide a right angled hex driver underneath?

Took the abs lines out in the end, over to the bench with the ABS unit! Purchased a new solenoid ABS Modulator Shuttle Valve Repair Kit (Wabco) SWO500030 Island 4x4 - Specialists in Land Rover and Range Rover Parts and accessories for all models. UK and worldwide mail order. (just in case) - although mine was fine!

Replaced the shuttle valve and carried out Option B ABS Mod - LAND ROVER CLUB V.I.

SORTED!!!!

SO HAPPY, after a year of constant 3 amigos - not again.

I left the original socket in when reassembly as it provides a seal against any oil, note the orings ;-)

Unclipping the lines from the bulkhead helps lift it a wee bit more, u can get a 1/4 drive socket in underneath.
